Moya is one of more than 70 volunteers who have signed up so far for the Broward County Medical Response Unit. Among the respondents are physicians, nurses, EMTs, paramedics and physician’s assistants, according to Broward County Medical Association CEO Cynthia Peterson. The volunteers vary in age as well, with some being medical students and some coming out of retirement to help. While the bulk come from the tri-county area, Peterson said one volunteer is flying down from Alberta, Canada.
